What it is	Computer Science at Western teaches you how to write programs, build software systems, and solve problems using computers and code. You choose a focus — such as game development, managing information systems, or engineering robust software — based on your interests. The program includes paid work terms alongside your studies, letting you apply classroom learning in real jobs and build professional experience before you graduate.	Mechatronics Engineering combines mechanical systems, electronics, software, and artificial intelligence to design machines that think and act on their own. Unlike a traditional engineering program, this one requires you to complete paid work terms alternating with school, giving you real industry experience building the robots and automated systems you study in class. It suits people who want hands-on problem-solving across multiple engineering disciplines and are ready to balance studies with work semesters.	Engineering at Western teaches you to design and build solutions to practical problems using mathematics, science, and materials. You choose a specialization like software, mechanical, civil, or chemical engineering, or study general engineering first before deciding. The program includes co-op work terms, so you alternate between classes and paid jobs with employers, giving you real experience alongside your degree.
